Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12774, here are decompositions:

11 + 12763 = 12774
17 + 12757 = 12774
31 + 12743 = 12774
53 + 12721 = 12774
61 + 12713 = 12774
71 + 12703 = 12774
103 + 12671 = 12774
127 + 12647 = 12774

Showing the first eight; more decompositions exist.
